СПАСИБО а вот это предложение посмотрите, ПЛИЗ. гарант по верно? тоже с рус

However K. Pittindger provides the same consultancy services to JSC NC which acts as a guarantor on the specified long-term project finance.

Однако, по тем же вопросам г-н К. Питтинджер оказывает консультационные услуги АО НК , выступающему гарантом по указанному долгосрочному проектному финансированию.

It's really good, but I would make the following changes.

-'consulting' instead of 'consultancy'
-'financing' instead of 'finance'
-maybe rethink 'of share of the Company'. It seems like there are too many 'ofs'. You could try 'of company ownership' or something like that.

Good luck!

[SigGolfer]

For the second sentence, remember to add commas after 'however' and 'NC'. Also, I would change 'consultancy' to 'consulting' and 'finance' to 'financing'. Other than that, the sentence looks good.

However K. Pittindger provides counseling on identical matters to JSC NC acting as a surety on the above-metioned/referred long-term project financing.

long-term project financing в данном случае

acts as a consultant.

Не надо identical. Не надо the same. Надо - similar.

В Вашем варианте Питтинджер не только консультирует, но и выступает в качестве гаранта ... Не surety, кстати, в данном случае

[SigGolfer]

_03 - Consultancy is mainly used in Britain and would be fine for a British audience. To most other English speakers, the correct term is 'consulting'. 'Finance' generally refers to the specific branch of Economics and not the actual act of 'financing', which is what the sentence seems to be talking about.
For your translation, I would take out 'identical. Also, you need 'which acts' after 'JSC NC', otherwise it means that Mr. Pittindger is acting as the guarantor.

Надо - similar. Докажите. Устанете. Дело вкуса. Хотел в принципе употребить similar.
surety - докажите.
