Ice Management Fleet

Although it is planned to operate in the open water season a four vessel Ice Management fleet was put together for the eventuality of operating in ice throughout the anticipated season.

A contingency contract for two additional conventional ice breakers is in place in case additional support is required for late season or demobilization operations.

The ice management fleet is structured as follows

1. One Vessel at each theatre designated as the primary Ice Management Vessel

2. One vessel at each theatre designated as the secondary Ice Management Vessel and Anchor Handler

Primary Ice Management Vessel

The primary IM Vessels conduct ice scouting missions far from the drilling unit confirming satellite imagery and assessing ice regimes with regard to the following

1. Hazard potential

2. Floe size

3. Stage of development

4. Set and drift

5. Manageability

The primary IM Vessels provide the information and advise required to operate the ice management Alert System

In addition these vessels are tasked with ROV and Dive operations as well as various science projects related to permitting

Secondary Ice Management Vessels

The secondary Ice Management Vessels generally work close in to the drilling unit and are tasked with the following

1. Monitoring ice up drift of drilling units

2. Pushing, breaking or prop washing ice away from the drilling unit

3. Anchor handling and laying the mooring system for the drilling units.

4. Towing drilling units

In addition the secondary IM Vessels can be sent on ice scouting missions as required

Emergency Resource

The vessels Shell has brought to the arctic provide a resource which has not been previously available.

In areas like the Gulf of Mexico, North Sea or other well developed areas of operation there are many resources from both government and private industry which may be called on in the event of emergency

The Shell fleet provides a number of resources which are of use in these situations.

1. Four Ice Class vessels capable of ocean rescue and salvage

2. Three vessels and two drilling units with helicopter decks suitable for S-92 helicopters

3. Medical facilities throughout the fleet.

Emergency Response To Marine EmergencyOn Friday, December 3, 2010, Shell was asked to assist in the rescue of the bulk carrier M/V Golden Seas that had lost power north of Atka Island.

The M/V Golden Seas was full of contaminant cargo and several hundred thousand gallons of bunker fuel oil. With 20 crew on board and limited power to its main engines, the Golden Seas was in danger of encountering rocks within hours.

Shell was immediately contacted for possible use of the ice-class anchor handler Tor Viking II – the same vessel Shell contracted to tow the Kulluk drilling unit to Dutch Harbor in the summer of 2010. The Tor Viking II was the only vessel in the region capable of assisting the M/V Golden Seas. On December 4, the Tor Viking II connected her tow wire to the M/V Golden Seas in 27-foot swells and began towing her to Broad Bay near Dutch Harbor. Both vessels safely arrived in on Tuesday, December 7.

Emergency Response

Shell’s close working relationship with the Coast Guard, federal agencies and DEC played a critical role in not only preventing an environmental catastrophe, but a human tragedy that became all too real to Alaskans two years ago when the M/V Selendang Ayu ran aground – killing six crew members, tearing the freighter apart and forcing a Coast Guard helicopter into the water. Assisting with the rescue of the M/V Golden Seas is just one example of Shell’s commitment to positively impacting the communities in which we work.
