Esnaad takes its first PSV from Shipyard De Hoop

Dutch Shipyard De Hoop has delivered first in a series of ten platform supply vessels (PSVs) to Esnaad, the operating company of the Abu Dhabi National Oil Company (ADNOC). 

The contract for these ten PSVs was awarded in 2013. Whilst the complete production of the vessels is equally split between the two facilities in Lobith and Foxhol, the delivery is spread over almost two years, with the last PSV to be handed over in 2017.

The first vessel, named Esnaad 221, was delivered to Esnaad on July 15, 2015. In the meantime, the hull of the second vessel has been launched in Foxhol, whilst the steel hull of the fourth PSV is currently being assembled on their slipway. At the Lobith facilities, the hull of the third vessel is ready to be launched, whereas the block sections of hull number five are being assembled on their second slipway. Furthermore, the shipyard says that the the steel cutting and construction of the first block sections for the sixth vessel is at an advanced stage.

The vessel’s main dimensions are 70.4×15.8metres (L x B).

The hull form of the PSV, with its specially developed bulbous bow, is optimised to reduce wave resistance. Most of this hull volume is dedicated to a large number of high-capacity tanks for various dry bulk and liquid cargoes, like brine, cargo fuel oil, drilling water and liquid mud. Furthermore, in the forward hull, where also the usual fuel oil, fresh water, sewage, sludge and bilge water tanks are integrated, are the foam and dispersant tanks for fire fighting and oil spill rescue actions.

In addition to the liquid cargo, the PSV will transport deck cargo on its 515sq.m work-cum-cargo deck, which permits large quantities of various offshore requisites of up to five tons per square metre. For loading and unloading duties a fully hydraulic telescopic boom type crane, with a lift capacity of 15tons at 2.5metre or 0.5ton at 25metres outreach is fitted to starboard side.

External fire-fighting tasks are performed with the two remotely controlled monitors on top deck, capable of spraying a water/foam mixture. Furthermore, the PSV is fitted with two six-metre spray booms, enabling crew to apply dispersant to the water surface in case of an oil spill.

In close consultation with the yard, ADNOC opted for diesel-electric propulsion. The three main generators, feeding the diesel-electric propulsion units and other consumers, are located below deck, in the fore ship underneath the superstructure. This was done to accommodate the preferred generators with the relatively large medium speed engines. The propulsion components comprise of three tunnel bow and two azimuthing stern thrusters, to achieve high-accuracy station-keeping and allowing for a transit speed of 13.5knots, both at the lowest possible power requirements.

The shipyard emphasized that the vessel offers accommodation to 28 people, all in cabins with en suite bathrooms, individually controlled air treatment units, radio, television and access to internet.
