SEABIRD PHASE II MEGAPROJECT, INDIA TERRAMARE’S INTERNATIONAL UNDERWATER DRILLING AND BLASTING SERVICES 01
T erramare has participated on the west coast of India in the Seabird Phase II megaproject, which is now in the finishing straight. The site is located in Karwar, Karnataka, where the Indian naval base INS Kadamba opened in 2005, after the completion of the first construction phase. In the Seabird Phase II project, launched in 2017, a new kind of naval base is being devel- oped by expanding existing harbour structures. The expansion will enable the more efficient stationing, operation and maintenance of fleet vessels. Seabird Phase II is a project of national significance for India. The project has been commissioned by the Indian Navy, assisted by the consultant firm Aecom. The extensive Seabird Phase II project also included underwater drilling and blasting, which was implemented by six Terramare hy- draulic drilling towers and other equipment, which were installed on the deck of a locally leased work pontoon. The underwater drilling and blasting project was the responsibility of the local company Boskalis Smit India LLP, which implemented the project in cooperation with Terramare, Rock Fall and Boskalis. The main contractor in the overall project is L&T – ISDPL JV, which is a con- sortium formed by the companies Larsen & Toubro Ltd and Interna- tional Seaport Dredging Pvt Ltd (ISDPL). Terramare barge masters Lassi Rantapelkonen and Henri Hulk- konen , from Finland, and the Boskalis barge master Andrew Gray , from Scotland, participated in the international underwater drilling and blasting team, which also included other experts from the UK, Portugal and India. Michael Seckington and Tristan Forsythe served as site managers. “I am very satisfied with the underwater drilling and blasting contract, which was implemented in a goal-oriented and profes- sional way. I would like to send my thanks for this to all members of our international team. I can also report that observations on the logistics and mobility of the underwater drilling and blasting
fleet and equipment were highly positive. It is great to know that, applying this effective concept, equipment can be packed for ship- ment and transported really quickly to sites anywhere around the world,” says Barge Master Lassi Rantapelkonen. “The working conditions were also nothing to complain about, even though the daily temperature was 30–35°C. The local traffic and culture are, of course, fascinating and lively compared to con- ditions back home, but this only enriches the field of experience in these international projects,” says Lassi. The underwater drilling and blasting included in the Seabird Phase II project was implemented in an area of 86,550 m 2 , from which a total of 63,811 m 3 of blasted rock was removed. The blasted rock was removed by Boskalis’ large 72-metre backhoe dredger Magnor (2,312 GT), which has a bucket capacity of up to 40 m 3 .
