Innovation through cooperation

By Tom Scott

For many maritime companies, cooperation with an
external party is a perfect way to develop innovative products and ideas. By
forming symbiotic relationships, both companies can concentrate on their core
businesses while drawing on the expertise of the other. The new branches of
knowledge that are formed advance the progress of technology in the maritime
sector. This article takes a closer look at the innovations originating from two
such cooperative partnerships. The first is between naval architectural and
engineering company C-Job and software design house NAPA, and the second is
between automation specialist Bachmann Electronic and closed-loop control
specialist Controllab.

C-Job first started working with NAPA in 2009. In the
last decade the two companies have worked on various projects together, one of
the most notable being Accelerated Concept Design. This is a design optimisation
method that automatically checks the operational feasibility of multiple design
variations during the initial stages of the ship design (the concept design
stage). Accelerated Concept Design uses genetic and steered algorithms to
create progressive generations of designs, each more efficient than the
previous generation. It is a technique that can be modified depending on the
function of the vessel in question. “Cargo capacity and fuel consumption are
important for a container vessel, and bollard pull and manoeuvrability are key
aspects of tug design,” says Thijs Muller, lead research & development at
C-Job Naval Architects. “You can change the parameters to fit the project
requirements. They can be fixed parameters such as a payload or deadweight. Or
they can be variable like the length of the vessel. A key point, however, is
that we can generate concept designs within shorter time spans and evaluate a
larger design space.”

“With traditional methods the outcome of ship design is typically based
on past experience,” explains Jan Furustam, sales
director at NAPA. “Therefore improvements based on this
learning-from-the-past method is a step-by-step process. Accelerated Concept
Design not only reduces lead-time, but makes it possible for the designer to
evaluate a vastly larger design space – with combinations of design parameters
– compared to traditional ways of working. This significantly increases the
efficiency in terms of economics, safety and environmental parameters and results
in better and more efficient ship designs.

“There are new possibilities arising every day for using
computational power in ship design – bringing trends such as big data, AI and
optimisation software to the maritime industry,” adds Furustam. “For us as a software
product company, C-Job is a perfect match to develop and market a software
solution with them. This optimisation-driven design using multi-objective
genetic algorithms has been around for decades, but this has always been at an
academic level. Accelerated Concept Design is turning this into a really
practical tool in ship design. Therefore
it is a win-win situation for both of us. We get to evaluate and develop our
software, and they get to use new tools to increase the efficiency of their
process.”

In addition to generating designs in a shorter
period of time, Accelerated Concept Design has the potential to reduce a
vessel’s capital expenses (largely defined by its weight) and operational
expenses (determined by its operational efficiency). Muller continues: “This
cooperative research with NAPA allows for radical innovations
leading to reducing total cost of ownership while removing uncertainty from the
whole ship design and construction process – giving our clients confidence in the
ship and reducing the risks.”

Because the software behind Accelerated Concept Design
executes the repetitive and labour-intensive tasks, this frees up more time of
the naval architect to concentrate on the innovative and creative aspects of
ship design. Take this idea a step further and it can point the designer into a certain design direction where
improvements can be found. “It can serve as an inspiration to consider more
‘out-of-the-box’ designs – ones that may perform better than the original
idea,” concludes Muller.

The second example of cooperation
leading to innovation involves Bachmann Electronic and Controllab. The two
companies have worked together since 2011 and made the decision to seal to
technical partnership in 2014. “This was simply a letter from the management –
there was no formal agreement because a signature is enough. Trust is the basis
of this relationship,” states Ronald Epskamp manager business unit maritime at
Bachmann. “In this way, we work independently from each other while still
completing some very exciting projects together, contributing to the
development and application of technology in the maritime sector. It is a very
nice way of working.”

“We have much more traction together”

The foundation of this particular
cooperative relationship is the way Bachmann’s PLC control systems work with Controllab’s
20-sim software. This software works as a simulation package for dynamic systems
including electrical, mechanical or hydraulic parts or combinations of these.
Controllab CEO Christian Kleijn gives the details: “A Bachmann controller in
the propulsion system of a ship, for example, sends back a lot of data. Our
software uses these data to create a ‘digital twin’, a digital version of this
system.”

One important advantage of the digital
twin is the fact that it allows testing in a simulated environment, also known
as Hardware-In-the-Loop. “HIL testing is the ideal way to let all sorts of
things go wrong with the system without hazarding the people involved in the
real system,” explains Controllab CTO Paul Weustink. “Our work with cranes or
offshore access gangways are good examples of this. HIL testing allows us to
test a lot of different scenarios in a short amount of time.”

HIL testing is also relevant when
talking about destructive testing, which is both expensive and associated with
the all too real issue of safety. To this end Controllab can carry out up to
200 destructive tests per day at their in-house HIL facilities.

“A nice way of working”

The concept of the digital twin can also be used during the operational phase of a dynamic system. “This could be if a shipping company wants to see how its fleet is performing over a long period. Or it could be more short-term, using real system data in a simulation to investigate how that system can operate more efficiently. We can carry out this process within a matter of hours.”

Bachmann’s relationship with Controllab demonstrates how two independent companies can work together, but still keep focused on their core businesses. “We can concentrate on providing the most stable and up-to-date framework with the newest multicore processors to enable powerful real-time performance,” says Joeri ten Napel key account manager maritime at Bachmann. “And Controllab’s knowledge allows them to support their clients’ specific applications. When we work together, their insight into our products is really worthwhile for our shared clients. It also means that we can help our clients much quicker – we have much more traction together. We can quickly translate our clients’ vision into an applicable technical solution.”

In March 2019, Magnesium Producers NEDMAG and TIMAB MAGNESIUM announced a strategic partnership to development and market the use of magnesium hydroxide in marine scrubber systems. The product that the two companies developed, called MH53S MARE, aims to offer vessel owners, operators and crews a safe and cost effective alkali source for their scrubber operations. NEDMAG sales manager Henk van den Berg discusses the benefits of this cooperative partnership in which TIMAB MAGNESIUM handles the distribution to the maritime industry, and NEDMAG supports the development of this environmentally friendly solution from a technical point of view.

This relates to the sales force and global supply chain. To ensure worldwide availability of MH53S MARE, it is important to use distribution channels already set up and to develop smart logistic solutions for new prospects.

A lot of activities have been initiated since the cooperation between NEDMAG and TIMAB MAGNESIUM became effective. Intensive contacts with the main shipping lines, engineering companies, etc. have resulted in several projects to convert to MH53S MARE and to optimise the use of this new alkali source.

MH53S MARE is a stable suspension with a different rheology compared to traditional alkalis such as caustic soda. To make the use of MH53S MARE a success, it is important to understand the specific properties of this product. By installing the right type of pump and recirculation circuit, it is proven that the use of MH53S MARE reduces the operational costs significantly. Furthermore, MH53S MARE is a non-hazardous material, which contributes positively to crew safety.

After several years of successful use of MH53S MARE on board several vessels, NEDMAG and TIMAB MAGNESIUM are proud to bring this solution to the industry on a global scale. By combining their strengths, the two partners aim at improving further technical support as well as optimising supply chain options available to every single vessel operator, all over the world. Moreover, production capacity at Nedmag has already been doubled in 2018, with an additional expansion planned to support the industry’s growing demand.
