The U.S. Army Corps of Engineers (USACE), New York District has partnered with the USACE Marine

Design Center to construct and deliver the new diesel-electric battery hybrid Drift Collection

Vessel DRIFTMASTER II to the New York District at Caven Point Marine Terminal in September 2024.

Upon delivery of the vessel, the vessel will replace the 75-year-old DCV DRIFTMASTER.

The DRIFTMASTER II is being currently under construction at ThomaSea shipbuilding in Houma, LA.

Ockerman Automation Consultants is under contract with the Marine Design Center to supply the

propulsion and the electronic suite consisting of four (4) Cummins diesel generators, two (2) 1500

HP electric propulsion motors, two (2) 150 HP bow thrusters, all major electrical panels, including

the 750 VDC Links, 480V main switchgear, shore power isolation and hotel load transformers, all

AC/DC inverters, the engine room and navigation control consoles, power management and Integrated

Control and Monitoring Systems, shore power connection panels, and a 3440 kWh 750VDC Energy Storage

System (ESS).

NY HARBOR at CAVEN POINT MARINE TERMINAL HYBRID VESSEL CHARGING SYSTEM

The equipment provided in this solicitation will be provided by the Government as Government

Furnished Equipment (GFE) to be installed under a separate construction contract to form part of

the new NY Harbor at Caven Point Marine Terminal Hybrid Vessel Charging System shore power station

at the Caven Point Marine Terminal. This new shore power charging station will provide 480VAC

3-phase power to the new diesel-electric battery hybrid DCV DRIFTMASTER II.

The power requirements for the new DCV DRIFTMASTER II while connected to shore power will be 480VAC

3-phase power delivered at 550A through three (3) parallel three conductor plus ground shore power

cables. These power requirements will provide sufficient power to recharge the ESS from a fully

discharged state to fully charged in 12 hours. The power requirements for the vessel while

connected to hotel power will be 480VAC 3-phase power delivered at 150A through one (1) three

conductor plus ground shore power cable to provide sufficient power to the vessel’s hotel loads in

a winter loading condition.

The Caven Point Marine Terminal is located within the New York Harbor at the entrance of the

Verrazano Narrows. The facility withstands hurricane force winds, frequent 40 knot winds, dust,

debris, foreign material, storm surges, and standing water. The facility is home port to three

large crane boat debris collection vessels, three patrol craft and multiple trailered survey and

patrol boats.
