A Vendor’s View on Cost Control in Megaprojects
The factors contributing to out-of-control costs and delayed deliveries of projects are many. They range from unrealistic early cost and time estimates and human factors to the effects of geopolitical events. As with most complex subjects, the reasons lie in the eye of the beholder—and the context from which the beholder draws conclusions.
At the recent Offshore Northern Seas 2014 conference in Stavanger, Linn Cecilie Moholt, chief executive officer of Karsten Moholt, offered a Tier 3 vendor’s view of cost drivers. The company provides engineering, installation, monitoring, and maintenance of electromechanical components to clients in energy, offshore, shipping, and subsea businesses.
Moholt said the Norwegian oil and gas industry’s competitiveness is reduced because of the region’s high salaries and low efficiencies. Examples of projects for which construction was contracted abroad to reduce costs include Det Norske’s Ivar Aasen (SMOE, a subsidiary of Sembcorp Marine, in Singapore) and Statoil’s Mariner (Daewoo Shipbuilding and Marine Engineering in South Korea), Aasta Hansteen (Hyundai Heavy Industries in South Korea), and Dagny (Daewoo).
Norway’s provision of education to its youth has led to a higher number of professionals than historically seen, Moholt said. Although it is positive overall, the change has shifted the makeup and the competence balance of the organization of the supply chain, has driven costs upward, and contributed to a lack of differentiation between theoretical and practical knowledge.
She emphasized that not all workers need to be professional engineers or academicians. “Value the people that work hands on with technology as much as the educated engineer,” Moholt said. The value of hands-on craftsmen, more common in the past, was their direct familiarity with parts and systems and the know-how to troubleshoot problems with equipment.
Moholt presented data from a Statoil report, which showed the increase in accumulated man-hours of work for two comparable operation, maintenance, and monitoring projects. There was a 70% increase in the number of man-hours used for as-build engineering and a 304% increase in man-hours related to life cycle information and as-build updates. Man-hours related to total cable lengths (in meters) increased by 37%, while passive fire protection (in square meters) increased by 68%. Moholt pointed out that the largest increases were in the engineering-related activities.
She suggested that operators improve their communication with Tier 3 suppliers at the beginning of a project and rely on their knowledge and expertise. By involving the suppliers early in a project, the differentiation between theoretical and practical knowledge may become more apparent.
Moholt also emphasized the need to distinguish between innovation and modification. “There is a perception in the industry that modification equals innovation,” she said. “However, simply changing a way of connecting something is not an innovation.” Such practices prevent standardization of basic components, she said.
Adhering to a standardized modern maintenance philosophy can also help control life cycle costs. Often, a mixed approach of systematic preventive, reliability centered, or predictive maintenance is applied over time and results in inconsistent repairs/modifications or failure.
Moholt encourages the repair of parts, when possible, instead of replacement. The industry tends to replace parts because of the perception that “the parts are no longer available.” However, with today’s reverse engineering capabilities, it is possible to make “obsolete” parts, she said.
Drones Take Off in the Oil Field, but How High Will They Fly?
Unmanned aerial vehicles are creeping up on ubiquity in the oil and gas industry, but their potential still firmly outweighs the actuality. A panel at the 2019 SPE Annual Technical Conference and Exhibition took a close look at the benefits of drones and at the tethers still holding back their use.
Kongsberg To Build Digital Twin for Shell’s Nyhamna Gas Facility
As part of the $11-million deal, Kongsberg will establish a dynamic virtual representation of the plant, which serves as a gas processing and export hub for the Shell-operated Ormen Lange in the Norwegian North Sea.
Equinor Awards Milestone Wireless Subsea Drone Contract
The $43-million deal with Saipem will utilize a wireless underwater intervention drone and an ROV for intervention work on the Njord field in the Norwegian North Sea. Equinor said the contract is the first ever from an operator for advanced wireless drone services.
