Nā Nīnau i Nīnau Pinepine ʻia:

Q: He aha ka ʻokoʻa ma waena o ASTM A252 Papa 2 a me Papa 3 no ka paila ʻana?
A: ʻOi aku ka ikaika o ka Papa 3 (345 MPa vs 240 MPa yield) a hoʻohana ʻia no nā kahua hohonu a i ʻole nā koi ukana kiʻekiʻe. ʻOi aku ka hoʻokele waiwai o ka Papa 2 a kūpono no ka hapa nui o nā noi kahua maʻamau (nā alahaka, nā hale, nā awa). E koho i ka Papa 2 no nā ukana maʻamau, Papa 3 no nā ukana kaumaha a i ʻole ka hoʻokele hohonu.

Q: Ke hoʻolako nei ʻoe i nā paipu A252 Grade 2 me ka uhi galvanized?
A: ʻAe. Hāʻawi mākou i ka galvanizing hot-dip e like me ASTM A123. ʻO ka lōʻihi loa no ka galvanizing he 12.5m. No nā paila lōʻihi, paipai mākou i ka uhi epoxy a i ʻole ka uhi bituminous.

Q: He aha ka lōʻihi loa hiki iā ʻoe ke hana no ka paipu paila Papa 2?
A: ʻO ka lōʻihi loa o ka ʻāpana hoʻokahi he 18m (JCOE) a i ʻole 24m (UOE). No nā lōʻihi a hiki i ka 60m, hoʻoheheʻe mākou i nā ʻāpana he nui mai ka ʻaoʻao a i ka hopena me nā hoʻoheheʻe puni SAW komo piha (100% UT i nānā ʻia). He mea maʻamau kēia no nā monopile makani ma waho.

Q: Pono anei ʻo ASTM A252 i ka hoʻāʻo hydrostatic?
A: ʻAʻole. ʻAʻole koi ʻo ASTM A252 i ka hoʻāʻo hydrostatic no ka mea ʻaʻole nā paipu pili e pale ana i ke kaomi. Eia nō naʻe, inā koi kāu papahana i ka hydrotesting (e laʻa, no ka piling hui pū ʻana a me ka lawe ʻana i ka wai), hiki iā mākou ke hana iā ia me ke kumukūʻai hou aku.

Q: He aha ka uhi i ʻōlelo ʻia no ka paila ʻana i ke kai i loko o ka wai paʻakai?
A: No ka hoʻokomo ʻana i ka wai kai, ua ʻōlelo ʻia ka epoxy kēpau lanahu (600-800 microns) a i ʻole ka epoxy ʻāpana aniani. No nā wahi splash zone, ke paipai nei mākou i ka FBE a i ʻole nā uhi epoxy mānoanoa. No ka wai maʻemaʻe a i ʻole ka lepo, ua lawa pinepine ka paipu ʻeleʻele maʻemaʻe a i ʻole ka ʻili i ʻaila ʻia.

Q: Pehea ʻoe e hōʻoia ai e ola nā wili i ka hoʻokele hāmare?
A: Hana mākou i ka hoʻāʻo pālahalaha (pono) a me ka hoʻāʻo kūlou alakaʻi ʻia ma nā laʻana weld. No nā paila i hoʻokele koʻikoʻi ʻia, hana pū mākou i ka 100% UT o ka weld seam a me MPI o nā manamana wāwae weld. Hiki iā mākou ke hāʻawi i ka hoʻāʻo hopena Charpy ma 0°C a i ʻole haʻahaʻa inā kuhikuhi ʻia.

Q: He aha ka manawa alakaʻi maʻamau no nā paipu paila Papa 2?
A: Ka manawa alakaʻi maʻamau: 25-35 mau lā no nā anawaena ≤ 1,422mm. No ka papa ʻōwili nui (> 1,422mm): 35-50 mau lā. No nā paila lōʻihi i hoʻopaʻa ʻia (a hiki i ka 60m): e hoʻohui i 2 mau pule.

Ua hala ka uhi ʻana i 3,000 hola o ka hoʻāʻo pīpī paʻakai (ASTM B117) me ka < 2mm creep mai ka scribe. ʻIke ʻana i ka Holiday ma 4kV me ka ʻole o nā hemahema.

●Nā puʻu lōʻihi no ka wahi moe hohonu– ʻO ka lōʻihi o ka paila i koi ʻia he 28m (18m i loko o ka papa kai + 10m ma luna o ka laina lepo). ʻO nā hui maʻamau 12m e pono ai i 3 mau ʻāpana kahua. Ua hoʻolako ʻo Womic i nā hui 18m lōʻihi (papa ʻōwili) no nā paila 1,016mm, e hōʻemi ana i nā ʻāpana kahua mai 3 a 2 no kēlā me kēia paila. No nā paila hoʻopaʻa koʻikoʻi, ua hoʻolako mākou i nā paila 28m lōʻihi ma ka hoʻoheheʻe ʻana i ʻelua mau ʻāpana 14m (100% UT i nānā ʻia).

●Nā hoʻoluhi hoʻokele kiʻekiʻe ma ke one mānoanoa– Aia i loko o ke ʻano lepo nā papa one mānoanoa me nā waiwai SPT N o 40-60. Ua kokoke nā koʻikoʻi hoʻokele pila i 70% o ka ikaika hua. Ua hana ʻo Womic i nā hoʻokolohua kūlou alakaʻi (radius kūlou 4t, 180°) me ka ʻole o nā māwae. ʻAʻole i hōʻike nā hāpana hoʻāʻo palahalaha i ka māwae ma hope o ka hoʻopalahalaha ʻana o 1/2 anawaena. Ua hōʻike ka mea kūʻai aku ʻaʻohe hemahema weld i ka wā o ka hoʻokele ʻana o 3,200 mau pila.

●Ka paʻakikī o ka hopena no ka hoʻokomo ʻana i ka hoʻoilo– Hiki i nā mahana hoʻoilo o Rotterdam ke hāʻule i -5°C. Ua hāʻawi ʻo Womic i ka Papa 2 me ka paʻakikī o ka mahana haʻahaʻa i hoʻonui ʻia (Charpy ma 0°C min 27J, i hoʻokō ʻia he 50-80J). ʻAʻole koi ʻia kēia e ASTM A252 akā ua hoʻohui ʻia e ka mea kūʻai aku ma ke ʻano he akahele.

●Nā hana hoʻokele waiwai i Maasvlakte– Ua hoʻouna ʻia nā paipu mai Shanghai a i Rotterdam ma o ka moku haki nui (35 lā). Ma muli o ka palena o ka wahi hoʻomoe ma ke kahua hoʻokuʻu, ua hoʻonohonoho ʻo Womic i ʻekolu mau hoʻouna ʻana ma luna o 4 mau mahina. Ua hoʻonohonoho ʻia kēlā me kēia hoʻouna me ka papa hana hoʻokele a ka mea hana. Ua hāʻawi ʻia nā 10,800 tons a pau i ka manawa.

● Hopena:Ua hoʻopau ʻia ka hoʻonui ʻana o ke kahua hoʻoili i ka hapaha 3 o 2024. Ua hala nā pou 3,200 a pau i ka hoʻāʻo ʻana i ka ukana ikaika (PDA) me ka hiki ke hāpai i ʻoi aku ma mua o nā koi hoʻolālā. Ua ʻōlelo ka mea kūʻai aku: "He maikaʻi loa ka maikaʻi o nā paipu a Womic a me ka hilinaʻi o ka lawe ʻana." ʻO Womic Steel i kēia manawa he mea hoʻolako i ʻae ʻia no nā papahana awa ʻo Rotterdam e hiki mai ana.
