FEBRUARY 21, 2014 — Teekay Offshore Partners L.P., the part of the Teekay empire that owns things like FPSOs and FSOs, is getting into the business of towing them around and installing them. It has agreed to acquire ALP Maritime Services B.V. (ALP), a Netherlands-based provider of long-haul ocean towage and offshore installation services.

As part of the transaction, Teekay Offshore and ALP have ordered four 300 t bollard pull, 89 m x 21 m Ulstein SX-157 towing and anchor handling newbuilds at Niigata Shipbuilding & Repair of Japan. They will be capable of 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.

Teekay Offshore says the fully built-up cost will be “approximately $260 million, which includes the cost of acquiring ALP.”

Teekay Offshore intends to finance the ALP acquisition and initial newbuilding payments through its existing liquidity and expects to secure long-term debt financing for the vessels prior to their deliveries in 2016.

“The strong fundamentals in offshore oil and gas, combined with the large orderbook of floating offshore assets including FPSOs, FLNGs and drill rigs, are expected to result in strong demand for the services of long-haul towing and anchoring handling vessels,” said Teekay Offshore CEO Peter Evensen. “We believe ALP’s operational capabilities and customer relationships in the growing long-haul ocean towage and offshore unit installation segment is a natural complement to Teekay Offshore’s existing offshore project offering, which will provide the partnership with another channel for accretive cash flow growth.”

ALP says that offshore floating productions units are increasing in size and value and that multi‐billion dollar field developments rely on floaters capable of operating on site for well over a decade without returning to a shipyard. The transport of these units from the building yard to site and their subsequent installation to the permanent mooring on site is very important to the success of a project.

There is a need for powerful, course-stable and reliable towing vessels that are in control of the object under any circumstances. The subsequent installation of the units to a field’s mooring and riser‐systems require vessels able to operate safely in close quarters, including lengthy heading control duties. Mooring leg maintenance and replacement operations demand vessels that comply with stringent in‐field DP II requirements.

The market requires a new ultra‐powerful versatile towing, positioning, hook‐up, survey and
maintenance vessel with the ability to offer flexible services throughout the production platform life‐cycle.

The four new Alp Future vessels feature the Ulstein X‐Bow design to provide course stability during long‐distance towing operations and improve ship‐handling in adverse weather conditions. Each will be powered by four MAK 18,000 kW/600 rpm engines.

The vessels will be classed DNV+ 1A1 Offshore Service Vessel+, Anchor handling, Towing, E0, SF, Iceclass 1B, Fifi II, Tmon, Bis, Dynpos-Autr, Naut-OSV(A), Clean design, Comf-V(3), BMW-T, Recyclable

They will be the first ultra‐long distance towing vessels that are designed according to
DP II DNV Dyn‐pos Autr notation. As a result, they will be able to perform lengthy heading control duties in DP Mode and comply with stringent infield DP requirements.
