US Naval Sea Systems Command (NAVSEA) has ordered a new vessel, to a Jensen design, for assisting its naval ships and submarines in and out of ports.
Crowley subsidiary Jensen Maritime Consultants is supplying one of its designs for a 14 m vessel that will become a manoeuvring workhorse for the US Navy. Apart from handling naval vessels, this workboat will also be used for towing barges, opening and closing security barriers and manoeuvring floating port operations support equipment.
This workboat’s propulsion system consists of ZF W325 marine gears and inboard diesel engines, twin Cummins QSM11-455. It will have two Pullmaster hydraulic deck winches for use in multiple mooring configurations and heavy-duty fendering for protection when performing these operations.
Jensen has included a H-bitt on the bow, mooring bitts at the shoulders and stern quarters, and an aft taff-rail for a smooth sweep of the tow hawser while towing astern. It has a lifting davit that can be mounted in three different locations on the stern, kort nozzles and flanking rudders to improve steering when operating in reverse.
It also has skegs for directional stability while underway and structural support to facilitate drydockings and transport, plus accommodation for five crew. It is due to be delivered from a Pacific Northwest boat builder in Q4 2018.
