![]() "We also optimized the jacket design and weight. This resulted in reduced risks and significantly less steel. "We proposed to utilize optimally the lift capacity of our vessel, the Hermod, and to install the jackets by lifting them instead of launching them from a barge. "Cooperating with Kvaerner, Earl & Wright in the US and Sembawang Shipyard in Singapore, we were able to offer a concept which was unconventional for this area. The Balder type of vessel enables the total duration of the installation to be shortened."Įdwin Goldman, HeereMac's business strategy and development manager, offers another example of changing requirements from the South China Sea, where last year the ACT joint venture completed the Huizhou development. It is not the lifting capacity of the vessel but its sea state behavior which makes the difference, as well as the deckload capacity. "From then on, the weather does not really matter. "The piles and tendons are loaded on the Balder deck when the weather is good," he explains. The work could perhaps be performed by a smaller vessel, but the planning would be less attractive and reliable. With its lift capacity, two cranes, extensive deck load capacity and its ability to work even in bad weather, the Balder is well qualified to do the job. Such meticulous placements require perfect planning. We will position these piles on the exact spot with a tolerance of just two feet horizontally and 1.0 degrees vertically." diameter must be installed with an overall length of 120 metres. Why? Imagine the Ram Powell water depth of 960 metres. "Heavy lifts are not involved," Meek points out, "yet still we use the Balder for these jobs. Shell Oil in the US, for example, has allowed Heeremac to demonstrate its capabilities three times: two years ago with the installation of the Auger TLP foundation, and now in 1996 with Mars and in 1997 with the Ram Powell TLP. Much to Meek's relief, some clients have already got to grips with Heeremac's new strategy. We render services to the offshore industry." We don't install platforms, not in the old sense. That's a general misunderstanding we are confronted with almost daily. With a fierce, dismissive sweep of his arm Heeremac's commercial and technology director, Jan Meek, emphatically makes his point: Heeremac positioning its vessels to meet changing development needs ![]() Installation of Mars and Ram Powell TLP foundations.Emphasis shifting from heavy lifts to precision placement
