The hang off frame will be the temporary storage location for the follower between two successive pile drivings. Alternatively, the pile follower can be hung off from the starboard crane with the 36\u201d ILT during the LCP transit from one pile location to the other. Once all the piles are driven, the follower will be laid back on the pile barge (Terras 339).<\/span><\/p>\n<p><span style=\"color: #000000;\"><strong>Pile Follower details<\/strong><\/span><\/p>\n<table style=\"height: 162px;\" width=\"793\">\n<tbody>\n<tr>\n<td width=\"91\"><span style=\"color: #000000;\"><strong>Length (m)<\/strong><\/span><\/td>\n<td width=\"91\"><span style=\"color: #000000;\"><strong>P<\/strong><strong>i<\/strong><strong>le Interface Diameter (in)<\/strong><\/span><\/td>\n<td width=\"91\"><span style=\"color: #000000;\"><strong>Hammer Interface Diameter (in)<\/strong><\/span><\/td>\n<td width=\"91\"><span style=\"color: #000000;\"><strong>W<\/strong><strong>e<\/strong><strong>i<\/strong><strong>g<\/strong><strong>ht in air (MT)<\/strong><\/span><\/td>\n<td width=\"84\"><span style=\"color: #000000;\"><strong>Position of\u00a0<\/strong><strong>Padeye from Top of follower (m)<\/strong><\/span><\/td>\n<td width=\"6\"><span style=\"color: #000000;\">\u00a0<\/span><\/td>\n<\/tr>\n<tr>\n<td width=\"91\"><span style=\"color: #000000;\">18.075<\/span><\/td>\n<td width=\"91\"><span style=\"color: #000000;\">60<\/span><\/td>\n<td width=\"91\"><span style=\"color: #000000;\">36<\/span><\/td>\n<td width=\"91\"><span style=\"color: #000000;\">25.62<\/span><\/td>\n<td colspan=\"2\" width=\"91\"><span style=\"color: #000000;\">2.8<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"color: #000000;\"><strong>Lift Information<\/strong><\/span><\/p>\n<table style=\"height: 268px;\" width=\"785\">\n<tbody>\n<tr>\n<td width=\"203\"><span style=\"color: #000000;\"><strong>P<\/strong><strong>a<\/strong><strong>ra<\/strong><strong>meter<\/strong><\/span><\/td>\n<td width=\"202\"><span style=\"color: #000000;\"><strong>V<\/strong><strong>a<\/strong><strong>l<\/strong><strong>ue<\/strong><\/span><\/td>\n<td width=\"202\"><span style=\"color: #000000;\"><strong>Unit<\/strong><\/span><\/td>\n<\/tr>\n<tr>\n<td width=\"203\"><span style=\"color: #000000;\">Weight in air<\/span><\/td>\n<td style=\"text-align: center;\" width=\"202\"><span style=\"color: #000000;\">25.62<\/span><\/td>\n<td style=\"text-align: center;\" width=\"202\"><span style=\"color: #000000;\">MT<\/span><\/td>\n<\/tr>\n<tr>\n<td width=\"203\"><span style=\"color: #000000;\">Rigging Weight in air<\/span><\/td>\n<td style=\"text-align: center;\" width=\"202\"><span style=\"color: #000000;\">4.1<\/span><\/td>\n<td style=\"text-align: center;\" width=\"202\"><span style=\"color: #000000;\">MT<\/span><\/td>\n<\/tr>\n<tr>\n<td width=\"203\"><span style=\"color: #000000;\">Total Lift Weight in air<\/span><\/td>\n<td style=\"text-align: center;\" width=\"202\"><span style=\"color: #000000;\">29.72<\/span><\/td>\n<td style=\"text-align: center;\" width=\"202\"><span style=\"color: #000000;\">MT<\/span><\/td>\n<\/tr>\n<tr>\n<td width=\"203\"><span style=\"color: #000000;\">On board lifting Max Hook load (25% DAF)<\/span><\/td>\n<td width=\"202\">&nbsp;<\/p>\n<p style=\"text-align: center;\"><span style=\"color: #000000;\">32.03<\/span><\/p>\n<\/td>\n<td width=\"202\">\n<p style=\"text-align: center;\"><span style=\"color: #000000;\">MT<\/span><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"203\"><span style=\"color: #000000;\">Max Load on each crane (45:55 split)<\/span><\/td>\n<td width=\"202\">&nbsp;<\/p>\n<p style=\"text-align: center;\"><span style=\"color: #000000;\">17.61<\/span><\/p>\n<\/td>\n<td width=\"202\">\n<p style=\"text-align: center;\"><span style=\"color: #000000;\">MT<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"color: #000000;\"><strong>O<\/strong><strong>perational \u00a0Parameters<\/strong><\/span><\/p>\n<p><span style=\"color: #000000;\">There is no heading restriction for LCP during follower upending and hang off operations.

The mooring piles are marked with specific identification numbers 1, 2, etc. The mooring piles also have depth markings along its length to monitor the pile penetration. The depth markings start at 11m from the bottom of the pile and continue to the top at every 1m. The top and the bottom of the pile is marked with a 100mm wide band around the outer circumference of the anchor pile. The location of the padeye is also marked with a longitudinal straight line on the pile.<\/span><\/p>\n<p><span style=\"color: #000000;\">Anchor piles 1 to 5 are 31.8m (shorter by 0.2m) in length and the remaining piles are 32m in length. The piles will be installed in a sequence starting from the centre of the barge (Terras 339) and then moving out to the portside and starboard side to maintain the barge (Terras 339) stability in the sequence identified on the barge (Terras 339) layout.<\/span><\/p>\n<p><span style=\"color: #000000;\">The ground chains of each mooring leg will be pre-connected to the respective piles. The piles will have to be upended with the main and port cranes. To ensure the main crane has sufficient hook height for upending, it will be required to boom up on both the cranes for some of the piles to minimize the crane radii on both the cranes and hence gain hook height. The 3 piles (pile #5, pile #7 and pile #9) towards the portside of the barge (Terras 339) will have to be lifted horizontally with the main crane and re-positioned at the pile #3 location prior to upending. This is required to be done to ensure that the port crane has sufficient lift capacity for the upending operation.<\/span><\/p>\n<p><span style=\"color: #000000;\"><strong>Not<\/strong><strong>e that despite the difference in pile lengths, all piles shall be considered to be same and hence any pile can be installed at any pile location. Also note that individual pile marking numbers are for ID purposes only and do not correspond to pile locations.<\/strong><\/span><\/p>\n<p><span style=\"color: #000000;\">The chain has to be installed using both the winches on material barge (Terras 339). At any given point, one of the winches (active winch) will take the catenary tension and the other winch (passive winch) will have a minimum slack and will act as a redundancy

Thus, chain tensioning operation will be performed under the instruction of Company\u2019s Design Engineering Contractor and Company Rep onboard the FSO who will ultimately provide acceptance of the tensioning operation.

Alternative headings suitability shall be evaluated onsite by field engineers. Refer 16002-EMA-OP-FSO-DWG-0039 for FSO\u00a0 headings during chain tensioning operations. The distance of the turndown sheave from the top of the chain stopper is approximately 5 meters, so it is anticipated that only 3 to 4 meters can be pulled in each stroke. Where each round of tensioning is greater than one stroke, multiple strokes on a single chain leg will be performed. The procedure for one stroke of chain tensioning is described below.<\/span><\/p>\n<p><span style=\"color: #000000;\">Chain catenary angle shall be measured using a digital inclinometer positioned on the chain stopper.
