GALLERY: ALP’s final Future Class vessel named

ALP’s last Future Class ultra-long distance towing and anchor handling vessel ALP Keeper has been christened recently in Tamano, Japan.

The ALP Keeper was constructed by Niigata Shipbuilding & Repair, Japan. It is one of four ultra-long distance towing and anchor handling vessels constructed for ALP Maritime Services, a subsidiary of Teekay Offshore Partners.

The vessel is a part of the shipowner’s ALP Future class, a series of towing vessels made for offshore installation and decommissioning of large FPSO units, FLNGs, and drill rigs.

The vessel is based on the Ulstein SX 157 design and has a service speed of 13 knots, while its top speed is 19 knots. With a fuel capacity of more than 3,500 m3, the ALP Keeper and the rest of the Future Class quartet can tow at full power for 45 days, sufficient for non-stop Trans-Atlantic/Indian and the Pacific Ocean towing operations without fuel calls. The vessel is 88.9 meters long and 21 meters wide.

The aim of the design was to have sufficient bollard pull and operational reliability to handle even the heaviest tows with only two vessels. All four vessels are classed with DNV’s Clean Design and Ice Class 1B notations, which allow operation in restricted zones. The ships can accommodate 35 people for long periods at sea.

To remind, three of the four Future Class vessels have already been launched. Namely, ALP Striker was launched from Niigata shipyard in October 2015 while its sister vessels, ALP Defender and ALP Sweeper, were launched in January and May 2016.
