The vessels of the SX157 design were developed in close collaboration with ALP Maritime. The vessels are outfitted with DP2 and anchor handling capacity in order to assist during the installation/hook-up phase for the towed objects.
The ALP Future Class family of vessels have a fuel capacity of 3400 m3 of IFO/MGO – sufficient for non-stop Trans-Atlantic/Indian, Pacific Ocean towing operations without fuel calls. These long distance towing vessels have bollard pull of 300+ tonnes, a service speed of 13 knots and a top speed of over 19 knots. Additionally, the vessels are equipped with dynamic positioning capability (DP II) allowing ultra-long distance towing, offshore installation and decommissioning of large floating production, storage and offloading (FPSO) units, floating liquefied natural gas (FLNG) units and floating drill rigs at the highest safety levels.
The ALP Future vessels measure approximately 88.9 metres long, weigh 4250 deadweight tonnes and reach maximum speeds of over 19 knots.
At the time of the contract signing, this was a new market to Ulstein, and the largest single contract so far to Ulstein Design & Solutions AS. Ulstein, in addition to providing the design, is also responsible for the deliveries of main components, such as engines, thrusters and propellers, winch, power distribution and thruster drives, control system and communication system.
When developing the design Ulstein had to ensure that each vessel has the sufficient bollard pull and operational reliability to handle even the heaviest tows by only two vessels. Environment and fuel efficiency have also been important criteria. The vessels are classed with DNV’s Clean Design and Ice Class 1B notations, which allow operation also in restricted zones. Additionally, they are equipped as anchor handling vessels including stern roller, a three-drummed winch with 400t hoisting capacity, and with chain lockers for rig chain. The ships have a comfortable and spacious accommodation reflecting long periods at sea.
