Offshore petroleum industry uses helicopters to transport the employees to and from installations. Takeoff and landing represent a substantial part of the flight risks for passengers. In this paper, we propose and analyze approaches to create a safe flight schedule to perform pickup of employees by several independent flights. Two scenarios are considered. Under the non-split scenario, exactly ...

Weather conditions have a significant impact on the installation of offshore wind turbines. The rules for set clear limits. These limits are usually based estimations various experts and not real assumptions measurements on-site. When speeds wave heights too high, work cannot be carried out, this leads to delays additional costs. Therefore, we out measurement campaign during rotor blades invest...

A large number of facilities and parts of the infrastructure of offshore oil and gas reservoirs worldwide are approaching or have exceeded their original design life. The petroleum fields are still producing substantial levels of hydrocarbons which are recoverable and profitable if the field’s lifetime is extended. Thus, parts of this infrastructure are being considered for use beyond their pla...

The optimal development planning of offshore oil and gas fields has received significant attention in recent years. In this paper, we present an efficient investment and operational planning model for this problem which is fairly generic, and is extended to include fiscal considerations. With the objective of maximizing total NPV for long-term planning horizon, the proposed non-convex multiperi...

As the offshore market faces deepwater production challenges, the oil and gas industry is investing in new technologies to bring down the costs in the subsea fields exploitation. A breakthrough technology solution is the development of a subsea centrifugal compressor module installed on the seabed, transporting the wellstream to a central platform or directly to shore. The typical application o...

The development of the Pelamis wave energy converter from its conceptual origins to its commercial deployment is reviewed. The early emphasis on designing for survivability and favourable power absorption characteristics focused attention towards a self-referenced articulated line-absorber in an attenuator orientation. A novel joint and control system allow the machine to be actively tuned to p...

As offshore exploration and development of oil fields reach water depths of 1,000 to 3,000 m, novel methods of anchoring production platforms become attractive due to cost savings associated with installation. Surface production systems that are viable in these water depths include Tension Leg Platforms (TLP), spar platforms, and laterally moored ship-shaped and semisubmersible vessels. Possibl...
