PARIS โ€” Commercial launch services provider Sea Launch AG on Feb. 24 announced the resignation of longtime executive Kjell Karlsen as president, saying he is leaving to pursue โ€œother opportunities outside the space industry.โ€

Bern, Switzerland-based Sea Launch is struggling to return to a sustainable launch rhythm from its oceangoing platform in the Pacific Ocean following a 2007 failure that led to Chapter 11 bankruptcy reorganization, its purchase by Russian interests and its subsequent headquarters relocation from California to Switzerland.

A February 2013 failure slowed Sea Launchโ€™s return to regular flight, but the company has maintained support from customers Intelsat and Eutelsat. The Eutelsat 3B satellite is scheduled for launch aboard a Sea Launch Zenit rocket in April.

Sea Launchโ€™s operation in international waters has left it, in effect, without a government home, meaning the heavy-lift vehicle โ€” based on Russian and Ukrainian technology โ€” does not have access to U.S. or Russian government launches.

Sea Launch has used its equatorial launch base to focus on the heaviest telecommunications satellites, in competition with Russiaโ€™s Proton and Europeโ€™s Ariane 5 rockets. 

A Land Launch version of the rocket, with whose owners Sea Launch has had occasionally fractious relations, has been operated on occasion from Russiaโ€™s Baikonur Cosmodrome in Kazakhstan, a northern location from which it can launch smaller satellites into geostationary transfer orbit.

In a Feb. 24 statement, Karlsen said the increased ownership of Sea Launch by RSC Energia, one of Russiaโ€™s biggest space-hardware builders and the provider of the Sea Launch rocketโ€™s upper stage, will permit the company โ€œto continue to innovate and create value for the worldโ€™s satellite operator community. โ€ฆ I am looking forward to working in a new industry with a new set of challenges.โ€

In a Feb. 24 interview, Karlsen said he is leaving Sea Launch on good terms and โ€œin excellent handsโ€ to join a friendโ€™s company in the Los Angeles movie-licensing industry. โ€œItโ€™s been more than 14 years and itโ€™s time for me to accept a different challenge,โ€ he said. โ€œI really believe at this point that Sea Launch is well-positioned in the market.โ€

Sea Launch Chief Executive Serguei Gugkaev said in a statement that the company regrets Karlsenโ€™s departure and wishes him well. โ€œWe have a strong leadership team in place with dedicated executives who are ready to assume his responsibilities and duties,โ€ he said.
