  • Arctic Tow Mission
    Glosten was contracted by Exxon Neftegas Limited for overall management of moving the ORLAN, a 325 feet square Concrete Island Drilling Structure (CIDS), from Prudhoe Bay, Alaska, to Sovietskaya Gavan in the Russian Far East for the Sakhalin I oilfield development project. The structure, completed in 1984 and christened Glomar Beaufort 1, was designed with a patented honeycomb system using pre-stressed reinforced concrete so it could withstand ice pressures of up to 130,000 psi.

    A Window of Opportunity

    Glosten’s challenge was to develop a routing plan to safely tow ORLAN out of Prudhoe Bay in the extremely short period of time when ice melt allowed safe passage to Barrow. Glosten also prepared the engineering, environmental and economic analyses associated with the complex logistics of delivering cargo across an undeveloped, exposed beach site in the Sakhalin Islands.

    Complete Preparation

    Prior to initiating the tow, Glosten assisted in developing a risk assessment and readiness review workshop, implemented a Health, Safety and Environmental (HSE) plan, and executed an HSE and Quality Assurance interface program to ensure that the support vessels were fully compliant. Glosten also prepared the routing plans for the 15,000-mile platform relocation, and created project management reports and reporting tools so that management could follow the project on a daily and weekly basis.

    Flawless Execution

    The tow was completed on time, within budget, and without incident. Glosten personnel were on on-site in Sakhalin to assist in planning and managing the remote beach landing operation of 50,000+ tons of oilfield cargo.
